Drone flight powered by lightweight hydrogen-producing pellets
At first glance, hydrogen fuel cells sound like a great power source for fixed-wing drones making long flights – they have much longer run times than batteries, and they emit no emissions other than water vapor. Unfortunately, the hydrogen typically has to be stored in large heavy pressurized tanks. Last month, however, a Raptor E1 electric drone made a successful test flight running on a unique new system that’s actually lighter than the lithium-ion battery it replaced.
